DIPP-Motion Pro 2D® software is a new computerized system for quantitative analysis of motion of an object on screen automatically. It has been reported that cineradiography has been performed to analyze hyoid and laryngeal movements during swallowing; however, due to cost and preparation time, this method has not yet reached the clinical application stage. To overcome these problems, we have devised a new computerized system for quantitative analysis of video fluorography images using commercial “DIPP-Motion Pro 2D” software. DIPP-Motion Pro 2D® enables the efficient analysis including motion image sequence analysis, automatic tracking, measurement of distance and velocity, and graph display. With this system, quantitative studies were performed to analyze swallowing movements in 6 subjects without dysphagia. The median hyoid bone movement is 1.03cm(X-axis),1.59cm(Y-axis). The median laryngeal movement is 0.91cm(X-axis),2.46cm(Yaxis).The maximum bolus speed is 99.15cm/sec. We can analyze swallowing function conveniently and effectively with this system. It also could display the data with visual information. Therefore, it may become a tool to analyze swallowing function quantitatively in clinical practice. It also allows us to effectively exchange information with other medical personnel and gain informed consent.

Therefore, it may become a tool to analyze swallowing function quantitatively in clinical practice. Furthermore, it helps us to effectively exchange information with other medical personnel and gain informed consent. Cineradiography has made it possible to perform detailed visual analysis of the second stage of swallowing (hyoid and laryngeal movements) . Due to cost and preparation time, this method has not yet reached the clinical application stage. To overcome these problems, we have devised a new computerized system for quantitative analysis of video fluorography images using commercial “DIPP-Motion Pro 2D® software.
